We only use this for drawPoints, a rarely used API. On local tests, this is just as fast with the CPU backend implementations.

While this was intended to be the first in a series of compute based rendering experiments, it hasn't really been worth the carrying cost. So lets shrink the complexity and and remove another shader to boot.

Fixes flutter/flutter#147184

At one point I was going to see if there was a cutover point where the GPU was faster and implement a threshold scheme, but getting rid of an extra shader is reasonable. Here are the comments on the original PR:
